An engineless aircraft might sound just a little bit scary, so we should note these planes won’t be used commercially anytime soon. This particular engineless aircraft works by riding mountain waves – the glider needs to reach several thousand feet in altitude, using a tow plane and cable, before it is released on it’s own to ride the Andes mountain waves. And it’s been done before. In 2006, the Perlan 1 reached an altitude of about 50,000 feet but the two pilots onboard the aircraft, Steve Fosset and Einar Enevoldson, wore borrowed NASA spacesuits, making it much more difficult to operate the aircraft. The Perlan II plans to have the pilots operate in a pressurized cabin and be provided with fresh oxygen from a rebreather system. The Perlan II, without crew, weighs in at about 1100 pounds – that’s including several scientific instruments, cameras and ground-communications equipment already on board. It even comes with two parachutes for the pilots in case of an emergency situation.

The Perlan Project, as it’s called, explained the mission of the Perlan II, “The Perlan 2 will fly to 90,000 feet at the edge of space to explore the science of giant mountain waves that help create the ozone hole and change global climate models. This will require the engineering of a spacecraft with glider wings that can fly in less than 3% of normal air density and at temperatures of minus 70 degrees C, conditions approximating the surface of Mars. These missions will provide education and inspiration for young people seeking careers of exploration and adventure in engineering and science.”

While the glider is not necessarily a prototype for future aircraft (no, we probably won’t be commercially flying to Mars anytime soon,) it has the potential to open up a whole new world of possibilities for space travel and exploration. Because the glider will operate in atmospheric conditions similar to those on Mars, it will provide space agencies with insight as to how a winged aircraft would operate on Mars’ own atmosphere. According to Allan McArtor, Chairman and CEO of Airbus, the Perlan II could potentially “pave the way for both future aviation on Mars and Earth-based commercial hypersonic aircraft.”

About Design Engine

We help designers, engineers, draftsmen, and mechanics get better jobs, earn more money, design better products and games, become more innovative and creative, and outshine their competition. Since 1994 we’ve trained thousands of designers and engineers from companies like Motorola, Caterpillar, John Deere, Harley Davidson, and NASA. We increase your software comprehension. But more than that, we increase your knowledge of specific design and engineering techniques. This means that using software becomes more graceful, effortless, and flexible for you on all your projects.

Our commitment is to provide the best training for the product design and development, industrial design and engineering community. DESIGN-ENGINE|EDUCATION strives to empower students and organizations to significantly increase their design and engineering capabilities through innovative and comprehensive training challenges. Our engineering, product design, and industrial design training methods are outside-the-box, rather than the typical classroom book training.
